Inu To Hasami Wa Tsukaiyou

A nonsense comical mystery. Harumi Kazuhito is a high school boy who loves books and is a fan of novelist Natsuno Kirihime. One day, he finds Kirihime writing at a cafe, about to be shot by a robber. He protects her from the attack but is killed instead. Through the supernatural power of a book-worm, he is reincarnated as a dachshund dog. Kazuhito (as a dog) writhes in a painful bookless life, when a sadistic woman carrying a pair of scissors offers him help. She is Kirihime herself. (Source: Dog and Scissors Wiki)
